API Reference

The Armatura Core API is organized around the StructuralModel class. You create a model, populate it with structural elements and loads, run analysis, and query results.

Typical workflow

// 1. Build
var model = new StructuralModel("My Structure");
// ... add nodes, members, supports, loads ...

// 2. Analyze
var results = model.RunAnalysis();

// 3. Query
var displacement = results.GetDisplacementEnvelope(nodeId);
var forces = results.GetMemberForces(memberId);
var governing = results.GetGoverningUtilization(memberId);

// 4. Save
var project = new ArmaturaProject("My Project");
project.AddModel(model);
project.Save("path/to/project");

Immutability

AnalysisResultSet is immutable after construction. You query it but never modify it. If you change the model and re-analyze, you get a new result set.

Thread safety

The model is not thread-safe for concurrent writes. Analysis can run on a background thread. The result set is safe for concurrent reads.
